The First Alert Onelink Safe and Sound is the newest smoke and Carbon Monoxide detector from the US based manufacturer and it is the second attempt at creating a worthy competitor to the widely popular Nest Protect 2nd Generation. I purposely skipped the first generation of OneLink because it was a mess software wise the app was unstable and the device would constantly trigger false alarms, so the company has worked hard to fix these issues and hoped that this new device would receive more positive feedback from the audience. To further set it apart from its predecessor and its competitors – which are not that many, the First Alert Onelink Safe and Sound has included a built in speaker and has embedded Alexa Voice Services, while also keeping the compatibility with Apple’s HomeKit of course, this has driven the price up significantly. Since the Halo Smoke Alarm got discontinued and the Cloud based support got closed as well, I can understand why people may be reluctant with giving start ups a chance and instead may prefer to go with a more mature company that’s been in the business for longer and that’s where the likes of Nest and OneLink Safe and Sound come into play and remain overall favourites in spite of the usually higher price tags. The First Alert Onelink Safe and Sound detector features a fairly large oval case made of plastic, with the front side divided into multiple inner sections by narrow plastic bands, the device mostly being covered by lots of puncture holes the middle section is slightly elevated. Surrounding the top area there’s a metallic ring while towards the bottom, the case gets significantly slimmer and it features narrow holes all around to allow the smoke to enter the inner chamber.
